Abstract
SE PROPORCIONA LA CONVERSION DE UN AMPLIFICADOR DE SEÑALES DE RF DESDE UNA CONFIGURACION DE SEÑALES NO EQUILIBRADAS A UNA CONFIGURACION DE SEÑALES EQUILIBRADAS, INCLUYENDO A LA VEZ UN CAPTADOR DE IMAGENES PARA AMBOS LADOS DEL CIRCUITO EQUILIBRADO. EL LATERAL PUESTO A TIERRA DEL SECUNDARIO DE UN CIRCUITO DOBLE SINTONIZADO (14, 16, 18, 20, 22) SE ELEVA DESDE EL SUELO PARA PROPORCIONAR UNA CONFIGURACION DE CIRCUITO EQUILIBRADO. SE DISPONE DE UN FILTRO ELIMINADOR EN LA CONFIGURACION DEL CIRCUITO EQUILIBRADO MEDIANTE UN PAR DE PEQUEÑOS CONDENSADORES (CS1, CS2) ACOPLADOS ENTRE LOS CONDUCTORES (26A, 26B) SECUNDARIOS EQUILIBRADOS A NODOS DE SEÑALES ADECUADAS.THE CONVERSION OF AN RF SIGNAL AMPLIFIER IS PROVIDED FROM AN UNBALANCED SIGNAL CONFIGURATION TO A BALANCED SIGNAL CONFIGURATION, INCLUDING AT THE SAME TIME AN IMAGE SENSOR FOR BOTH SIDES OF THE BALANCED CIRCUIT. THE SIDE GROUND SIDE OF A TUNED DOUBLE CIRCUIT (14, 16, 18, 20, 22) RISES FROM THE FLOOR TO PROVIDE A BALANCED CIRCUIT CONFIGURATION. A REMOVAL FILTER IS AVAILABLE IN THE BALANCED CIRCUIT CONFIGURATION THROUGH A PAIR OF SMALL CAPACITORS (CS1, CS2) COUPLED BETWEEN THE SECONDARY CONDUCTORS BALANCED TO NODES OF SUITABLE SIGNALS.
